Introduction:
Mold growing on caulk is a common yet frustrating issue in bathrooms, kitchens, and laundry rooms. It not only looks unpleasant but can also lead to health concerns if left untreated. Fortunately, you don’t need to replace the caulk every time mold appears. With the right tools and techniques, you can eliminate mold safely and restore cleanliness to your home. In this DIY guide, we’ll walk you through simple, effective steps to remove mold from caulk and prevent it from returning.
Ingredients (Supplies) Needed:
White distilled vinegar or hydrogen peroxide (3%)
Baking soda (optional for paste)
Spray bottle
Old toothbrush or small scrub brush
Rubber gloves
Safety goggles (optional but recommended)
Paper towels or clean cloths
Mild dish soap
Plastic wrap (optional for stubborn mold)
Preparation:
Ensure Ventilation:
Open windows or turn on an exhaust fan. Mold removal involves fumes and disturbed spores, so air circulation is important.
Initial Cleaning:
Wipe the area with warm, soapy water to remove surface grime.
Apply the Cleaner:
For vinegar: Spray undiluted white vinegar directly onto the moldy caulk.
For hydrogen peroxide: Spray 3% hydrogen peroxide directly onto the mold.
Optional: Make a paste with baking soda and a little water or vinegar for extra scrubbing power.
Let It Sit:
Allow the solution to sit for at least 10–15 minutes. For stubborn mold, cover the area with plastic wrap to keep it damp and extend the soaking time up to an hour.
Scrub Thoroughly:
Use a toothbrush or small brush to scrub away mold. Reapply the solution as needed while scrubbing.
Rinse and Dry:
Rinse with clean water and wipe the area with a dry cloth or paper towels.
Inspect and Repeat (if necessary):
If mold remains, repeat the process. Some deeply embedded mold may take 2–3 cycles to fully remove.
Tips for Presentation and Storage:
After cleaning, keep the caulk area dry by wiping it down after each use.
Use a mildew-resistant caulk when replacing old caulk to prevent future growth.
Keep a spray bottle of vinegar in the bathroom to mist problem areas weekly.
